Common Questions about Rational Expressions

To simplify a rational expression, you need to factor both the numerator and denominator. This involves breaking down the polynomials into their prime factors and canceling out any common factors. For example, consider the rational expression (x^2 + 4) / (x + 2). To simplify this expression, factor the numerator and denominator to get ((x + 2)(x - 2)) / (x + 2). Canceling out the common factor (x + 2) results in the simplified expression (x - 2).
